There's this one:
1. (a) All songs must be ORIGINAL, NEW MATERIAL, released on or after January 1st, 2023. Exceptions will be made in the following circumstances:
(i) A song released as a single no more than 6 months before the cut-off date may ONLY be chosen if that song was subsequently released on an album for the first time during the official period of eligibility. For example, a song which was released as a single on July 1st, 2022 may be chosen if that song was later included in an album released on January 1st, 2023 or thereafter.
But if the album was also released in 2022, the song can't be eligible.
